Thanks lots for that; yes, I had been worried what I would do if it somehow got bricked; and not able to re-flash stuff as I've been able to do after the PR1.2 upgrade broke it (back when I had working usb). My regular (builtin) backup app is also a bit broken for some other reason (happened same time as this audio system breakdown) and not due to a lack of drive space, so backupmenu seems like a good tool to have. I haven't researched enough what to re install to fix this and a couple of other minor things though.
